Printable dielectric elastomers of high electromechanical properties based on SEBS ink incorporated with polyphenols modified dielectric particles

In this work, a recently developed 3D additive processing technology termed electrohydrodynamic (EHD) printing was employed to fabricate dielectric elastomer (DE) films by using styrene-ethylene-butylene-styrene (SEBS) inks with the addition of high titanium dioxide (TiO2) nanoparticles. order improve dispersibility TiO2 in SEBS matrix, extracted walnut polyphenols were utilized for surface modification nanoparticles labelled wp-TiO2. The effect applied voltage on ink jet morphology obtained based during EHD analyzed. prepared had precision patterned shapes and their studied. It revealed that matrix compatibility greatly improved procedure. Furthermore, printed DE found have excellent mechanical, electromechanical properties. For range DEs fabricated, SEBS/10%wp-TiO2 composite exhibited maximum actuated area strain 21.5% at an electric field about 34.0 V/?m without degradation other
